Question

mr Smith is flying his single engine plane at an altitude of 2400 feet. he sees a cornfield at an angle of depression of 30 degrees. what is his horizontal distance to the corn field?

Answer 1

Let the horizontal distance be represented with x

By Trigonometric Ratio,

`\begin{gathered} \tan 30=(2400)/(x) \\ \text{cross multiply, we get,} \\ x=\text{ }(2400)/(\tan30)=\text{ 4156.922}\approx\text{ 4156.9 fe}et \end{gathered}`
